Abstract

UN APARATO DE ALMACENAMIENTO Y CONVERSION DE ENERGIA (1) QUE COMPRENDE UN CONFINAMIENTO (5) QUE DEFINE UNA CAMARA DE VACIO (7), UN EJE DE SOPORTE (9) DISPUESTO DENTRO DE LA CAMARA DE VACIO (7), UN ESTATOR (11) DISPUESTO SOBRE EL EJE (9) Y UN ROTOR CILINDRICO (13) QUE, DURANTE SU USO, ES ACCIONADO POR EL ESTATOR (11) PARA QUE ALMACENE ENERGIA A MODO DE ENERGIA CINETICA DEL ROTOR (13) Y ACTUA CON EL ESTATOR (11) COMO GENERADOR PARA LIBERAR ENERGIA , QUEDANDO EL ROTOR (13) SOPORTADO POR EL EJE (9) A TRAVES DE UN CAPUCHON FINAL (29) QUE, CONFORME AUMENTA LA VELOCIDAD DEL ROTOR (13), SE TRANSFORMA DE TENER UNA FORMA CONICA A TENER UNA PLANA. EL RESULTADO ES QUE EL APARATO (1) NO SE AVERIA CUANDO EL ROTOR (13) SE EXPANDE COMO CONSECUENCIA DE LAS FUERZAS CENTRIFUGAS. ADEMAS, LA POSICION DEL ROTOR (13) RESPECTO AL ESTATOR (11) Y A UN COJINETE MAGNETICO QUE HAY SOBRE EL EJE (9) SE MANTIENE SUSTANCIALMENTE CONSTANTE, INCLUSO CUANDO EL LARGO DEL ROTOR (13) DISMINUYE DEBIDO A LOS EFECTOS DE POISSON.AN ENERGY STORAGE AND CONVERSION DEVICE (1) THAT INCLUDES A SETTING (5) DEFINING A VACUUM CHAMBER (7), A SUPPORT AXLE (9) ARRANGED INSIDE THE VACUUM CAMERA (7), A STATOR (11 ) PROVISION ON THE AXIS (9) AND A CYLINDRICAL ROTOR (13) WHICH, DURING ITS USE, IS OPERATED BY THE STATOR (11) TO STORE ENERGY IN THE MODE OF THE KINETIC ENERGY OF THE ROTOR (13) AND ACT WITH THE STATOR (11 ) AS A GENERATOR TO RELEASE ENERGY, THE ROTOR REMAINING (13) SUPPORTED BY THE AXIS (9) THROUGH A FINAL CAPUCHON (29) THAT, ACCORDINGLY INCREASES THE ROTOR SPEED (13), IS TRANSFORMED TO HAVE A CONICAL FORM TO HAVE ONE FLAT. THE RESULT IS THAT THE APPLIANCE (1) WOULD NOT FAIL WHEN THE ROTOR (13) IS EXPANDED AS A CONSEQUENCE OF THE CENTRIFUGAL FORCES. IN ADDITION, THE POSITION OF THE ROTOR (13) REGARDING THE STATOR (11) AND A MAGNETIC BEARING THERE IS ON THE AXIS (9) IS MAINTAINED CONSTANTLY, EVEN WHEN THE ROTOR LENGTH (13) DECREASES DUE TO THE EFFECTS OF POISSON.
